ABSTRACT:
A bird feeder having a squirrel guard which prevents squirrels from reaching the bird seed held by the feeder. The squirrel guard is mounted on the base of the feeder and includes roller elements which extend completely around its perimeter. The roller elements are positioned so they must be gripped by the animals, and the elements then rotate to prevent or grip secure enough to allow the animal to climb past the squirrel guard onto the feeder. The guard can also be used by itself to protect posts and trees against climbing animals.
